Turning to FIG. 29, steering assembly 160 includes a steering post 500, a left fork 502A, and a right fork 502B. Steering post 500 of steering assembly 160 passes through a fork journal 504 of front frame member 140 as shown in FIG. 30. Sealed bearings 524 and 526 are pressed into a top portion and a bottom portion of fork journal 504 and facilitate the rotation of steering post 500 relative to front frame member 140. Left fork 502A is positioned on a left side of front frame member 140 and right fork 502B is positioned on a right side of front frame member 140. As shown in FIG. 33, fork journal 504 is generally positioned forward of left fork 502A and right fork 502B. As such, steering post 500 is generally positioned forward of left fork 502A and right fork 502B.

In addition, steering post 500 is angled relative to forks 502. Steering post 500 has a steering axis 506 which is angled relative to an axis 508A of left fork 502A. Right fork 502B also includes a fork axis which is parallel with fork axis 508A. Referring to FIG. 33A, steering axis 506 makes a first angle (∠SA) with a horizontal plane, illustratively the ground 114. This results in a caster angle (∠CA) of ninety minus the value the first angle (∠SA). Fork axis 508A makes a second angle (∠FA) with the ground. Both first angle (∠SA) and second angle (∠FA) are acute angles. First angle (∠SA) is larger than second angle (∠FA). In one embodiment, first angle (∠SA) is equal to about 65 degrees and second angle (∠FA) is equal to about 61 degrees. In one embodiment, each of first angle (∠SA) and second angle (∠FA) are between about 5 degrees and about 70 degrees. In one example, first angle (∠SA) is up to about 70 degrees and second angle (∠FA) is up to about 60 degrees. In one example, the difference between first angle (∠SA) and second angle (∠FA) ((∠SA)−(∠FA)) is up to about 10 degrees.

The position of steering post 500 results in steering axis 506 intersecting ground 114 at a point SA which is a distance TR_(S) from a wheel contact point, WC. TR_(S) corresponds to the amount of trail of vehicle 100. In one embodiment, TR_(S) is equal to about 5.2 inches. In one embodiment, TR_(S) is at least about 2 inches. In one embodiment, TR_(S) is up to about 8 inches. In one embodiment, TR_(S) is in a range from about 2 inches to about 8 inches. In one embodiment, TR_(S) is in a range from about 3 inches to about 6 inches.

In one embodiment, fork axis 508 passes through front wheel axis 227. In one embodiment, both fork axis 508 and steering axis 506 pass through front wheel axis 227.

In one embodiment, steering post 500 is forward of fork 502 and angled upward relative thereto to balance the steering effort between when vehicle 100 is configured as vehicle 10 and as vehicle 20. Referring to FIG. 34, a center of mass 520 for a steering support assembly 510 (see FIG. 1) of vehicle 10 is shown along with a center of mass 522 for a steering support assembly 512 (see FIG. 10) of vehicle 20. Both center of mass 520 and center of mass 522 correspond to the components which are supported by steering assembly 160 in vehicle 10 and vehicle 20, respectively, and not the overall center of mass for vehicle 10 and vehicle 20, respectively. Steering support assembly 510 includes all of the components of vehicle 10 supported by steering assembly 160 and includes removable windshield 164 and front light assembly 166. Steering support assembly 512 includes all of the components supported by steering assembly 160 for vehicle 20 and includes front fairing assembly 168, windshield 170, and front light assembly 172. In one embodiment, steering support assembly 510 weighs about fifteen pounds and steering support assembly 512 weighs about thirty-five pounds. Additional details regarding the components included within steering support assembly 510 and steering support assembly 512 are provided herein in FIGS. 36-43.

In the illustrated embodiment, center of mass 520 is positioned between steering axis 506 and fork axis 508 while center of mass 522 is positioned forward of both steering axis 506 and fork axis 508. In the illustrated embodiment, center of mass 520 is positioned about 13 inches rearward of front wheel axis 227 and about 25 inches above front wheel axis 227 and center of mass 522 is positioned about 11 inches rearward of front wheel axis 227 and about 26 inches above front wheel axis 227. Mass supported by steering assembly 160 affects the handling of vehicle 100 much more than the mass in saddle bag 184 and 186. By having steering axis 506 split center of mass 520 and center of mass 522 the handling of vehicle 100 is improved regardless of whether vehicle 100 is configured as vehicle 10 or vehicle 20. In one embodiment, center of mass 522 is about 1.10 inches forward of steering axis 506 (measured along a normal to steering axis 506—see FIG. 34) and center of mass 520 is about 1.14 inches rearward of steering axis 506 (measured along a normal to steering axis 506—see FIG. 34). By having the steering axis 506 pass between center of mass 520 and center of mass 522 the distance from each of center of mass 520 and center of mass 522 to steering axis 506 may be minimized. In one embodiment, steering axis 506 intersects center of mass 520. In one embodiment, steering axis 506 intersects center of mass 522.

Returning to FIG. 29, steering post 500 and fork 502 are coupled together through a plurality of coupling members. Illustratively, an upper triple clamp 530 and a lower triple clamp 532 are shown. Steering post 500 is received in an opening 528 of lower triple clamp 532 and secured thereto with a snap ring 529 (see FIG. 34). Portions 533 of fork 502 are received in openings 534 of lower triple clamp 532. Portions 533 are secured to lower triple clamp 532 through couplers 536 which cause the size of openings 534 to contract and clamp around portions 533. Since steering axis 506 is angled relative to fork axis 508, opening 528 is set at a different angle than openings 534.

Turning to upper triple clamp 530, upper portion 541 of forks 502 are received in openings 542 in upper triple clamp 530. Prior thereto, plugs 540 are placed in upper portion 541 to seal an interior of upper portion 541. Upper portions 541 are secured to upper triple clamp 530 through couplers 544 which cause the size of openings 542 to contract and clamp around upper portion 541. Caps 546 are placed over openings 542.

Steering post 500 is also secured to upper triple clamp 530. However, since steering post 500 is angled relative to forks 502, the size of the opening 548 in upper triple clamp 530 for steering post 500 is oversized so that steering post 500 may be received in opening 548. A spacer 550 is placed on top of sealed bearings 524 prior to upper triple clamp 530 being placed over steering post 500. A coupler 552 is threaded onto steering post 500 to secure steering post 500 to upper triple clamp 530. Coupler 552 includes a chamfered side which centers steering post 500 relative to opening 548 as shown in FIG. 34. This arrangement allows steering post 500 and forks 502 to be coupled to upper triple clamp 530 and lower triple clamp 532 while maintaining upper triple clamp 530 and lower triple clamp 532 generally parallel.

Referring to FIG. 35, in one embodiment coupler 552 is replaced with a spacer 554 and a coupler 556. Spacer 554 is generally hat-shaped and includes an upstanding portion 558 which centers steering post 500 relative to upper triple clamp 530.

By having the size of opening 548 be oversized, the complexity of the assembly vehicle 100 is reduced. Forks 502 may be assembled to lower triple clamp 532 off line and then brought to the main assembly line for assembling to frame 140. The added complexity with vehicle 100 is due to the fact that steering axis 506 is not parallel to fork axis 508. When the fork legs and the steering axes are non-parallel, more clearance between the steering post and the top triple clamp is needed in order to achieve this assembly step. However, once the parts are assembled, tight clearances between the top triple clamp and the steering post are required in order to minimize play in the steering assembly and ensure that the front wheel does not deflect laterally or longitudinally due to slippage between the top triple clamp and the steering stem.

In one embodiment, the steering assembly is assembled as follows. Lower triple clamp 532 and steering post 500 are assembled together with sealed bearing 526 placed around steering post 500. This assembly is mounted in a fixture to hold it. Left and right fork members 502 are assembled to the assembly. Couplers 536 are tightened partway to couple forks 502 to lower triple clamp 532. Front wheel 110, front fender 190, and other components, such as brakes, are coupled to forks 502. This assembly, referred to herein as the front subassembly, is then moved to the main production line for assembly to front frame member 140. The front subassembly is placed into a manipulator and assembled to the frame 140 which already contains sealed bearings 524 and the race for sealed bearings 526. Spacer 550 is coupled to steering post 500. Upper triple clamp 530 is placed over the fork legs 502 and steering post 500. Upper triple clamp 530 is slid down until it bottoms out on spacer 550. Assuming the embodiment in FIG. 35 is being implemented, spacer 554 is installed in upper triple clamp 530 to center upper triple clamp 530 on steering post 500. Coupler 556 is coupled to steering post 500. All of couplers 544 and couplers 536 are tightened to secure forks 502 to upper triple clamp 530 and lower triple clamp 532, respectively.

Referring to FIG. 31, for vehicle 10 handlebar 162 is coupled to upper triple clamp 530 through a handlebar riser 560. Handlebar riser 560 is inserted into openings 562 (see FIG. 29) in upper triple clamp 530 and is secured to upper triple clamp 530 with couplers 564. Handlebar riser 560 includes a clamp portion 565 which secures handlebar 162. Clamp portion 565 is tightened through couplers 568. Illustratively, couplers 568 are screws which may be tightened to secure the orientation of handlebar 162 relative to upper triple clamp 530 and loosened to permit adjustment of the orientation of handlebar 162 relative to upper triple clamp 530. This permits the easy adjustment of handlebar 162 without removal of the fairing.

Referring to FIG. 32, in vehicle 20 handlebar 162 is coupled to upper triple clamp 530 through a handlebar riser 570. Handlebar riser 570 is inserted into openings 562 (see FIG. 29) in upper triple clamp 530 and is secured to upper triple clamp 530 with couplers 574. Handlebar riser 570 includes a clamp portion 575 which secures handlebars 162. Clamp portion 575 is tightened through couplers 578. Illustratively, couplers 578 are screws which may be tightened to secure the orientation of handlebar 162 relative to upper triple clamp 530 and loosened to permit adjustment of the orientation of handlebar 162 relative to upper triple clamp 530. This permits the easy adjustment of handlebar 162 without having to remove steering support assembly 512.

As shown in FIGS. 31 and 32, the size of handlebar riser 570 is different than handlebar riser 560. This is to take into account the ergonomics for each of vehicle 10 and vehicle 20. In one embodiment, handlebar risers 560 and 570 result in left grip 163 and right grip 165 being in generally the same location for vehicles 10 and 20.

As mentioned herein vehicle 100 has two configurations, a non-fairing configuration 10 and a fairing configuration 20. For vehicle 10, a first steering support assembly 510 is provided. For vehicle 20, a second steering support assembly 512 is provided. The components of steering support assembly 510 and steering support assembly 512 are both supported by one or both of upper triple clamp 530 and lower triple clamp 532.

A threaded stud 606 which extends down from headlight bucket 604 passes through an opening 608 in an alignment support 610, an opening 611 (see FIG. 38) in support 602, and an opening 612 in a spacer 614. A threaded nut 616 is coupled to threaded stud 606.

Headlight bucket 604 is isolated from support 602 through rubber isolator 618 and rubber isolator 620. Rubber isolators 618 and 620 are positioned so that there is no metal to metal contact between support 602 and headlight bucket 604. This reduces the transfer of vibrations from support 602 to headlight bucket 604.

Turning to FIG. 38, the components of a lighting unit 622 of headlight bucket 604 are shown. Lighting unit 622 includes a low beam bulb 623 positioned proximate a first reflector 624 and a high beam bulb 626 positioned proximate a second reflector 628. Light produced by either low beam bulb 623 or high beam bulb 626 passes through an optical window 630. In one embodiment, low beam bulb 623 is an HID bulb and high beam bulb 626 is a halogen bulb. An HID ballast 632 for low beam bulb 623 is provided within the same housing 634 of headlight bucket 604 that includes low beam bulb 623.

Lighting unit 622 may be aimed as follows. An opening 636 is provided in housing 634 through which threaded stud 606 extends. Opening 636 is oversized to permit the movement of housing 634 in direction 640 and direction 642 relative to threaded stud 606. Threaded stud 606 is threaded into a cylindrically shaped coupler 644. In one embodiment, threaded stud 606 and cylindrically shaped coupler 644 are integrally made. Coupler 644 is positioned in a cylindrical portion 646 of housing 634. In a similar fashion, alignment support 610 has a cylindrically shaped cradle 648 which receives cylindrical portion 646 of housing 634. The positioning of threaded stud 606 in opening 608 generally maintains the relative rotational position of cylindrically shaped coupler 644 and cylindrically shaped cradle 648. However, due to the larger size of opening 636, cylindrical portion 646 is rotatable in direction 640 and direction 642 relative to cylindrically shaped cradle 648 to adjust the aim of lighting unit 622.

A user may loosely tighten threaded nut 616 onto threaded stud 606 such that cylindrical portion 646 is positioned in cylindrically shaped cradle 648. The user may then grasp housing 634 to rotate housing 634 in one of direction 640 and direction 642. Once an orientation of housing 634 is selected, the user would tighten threaded nut 616 to secure the orientation of housing 634 relative to cylindrically shaped cradle 648.

As shown in FIG. 38 and illustrated in FIG. 37, light assembly 600 is coupled to lower triple clamp 532 through a pair of couplers 656. In one embodiment, couplers 656 are bolts which are threaded into openings 654 provided in a tab 658 of lower triple clamp 532. As shown in FIG. 37, support 602 also supports a left turn signal unit 660 and a right turn signal unit 662.

Turning to FIG. 39, steering support assembly 510 also includes a removable windshield assembly 670. Removable windshield assembly 670 includes removable windshield 164 which is sandwiched between a front member 672 and a rear member 674. Front member 672 and rear member 674 are coupled together through a plurality of couplers 676. Exemplary couplers include carriage bolts and acorn nuts. Couplers 676 also couple rear member 674 to brackets 678 which couple removable windshield assembly 670 to upper triple clamp 530 and lower triple clamp 532.

Referring to FIG. 40, a first coupler 680 is threaded into lower triple clamp 532. A rubber isolator 682 is carried by first coupler 680. A rigid spacer 684 is positioned between first coupler 680 and rubber isolator 682. Exemplary rigid spacers may be made of metal, plastic, or other types of materials. An open-ended slot 686 of bracket 678 may be positioned over a reduced diameter portion 688 of rubber isolator 682 and is captured laterally between portion 690 of rubber isolator 682 and portion 692 of rigid spacer 684.

A second coupler 694 is threaded into upper triple clamp 530. In one embodiment, second couplers 694 are thumb screws with a knurled surface 704. A rubber isolator 696 is carried by second coupler 694. A rigid spacer 698 is positioned between second coupler 694 and rubber isolator 696. Exemplary rigid spacers may be made of metal, plastic, or other types of materials. Rigid spacer 698 abuts surface 700 of upper triple clamp 530 and provides a stop surface 702 to prevent over-tightening of second coupler 694.

As shown in FIG. 40, the mounting of removable windshield assembly 670 is directly to upper triple clamp 530 and lower triple clamp 532. Further, removable windshield assembly 670 may be removed without leaving any brackets behind. As such, if an operator wants to ride vehicle 10 without removable windshield assembly 670, vehicle 10 still provides a clean, attractive look. When removable windshield assembly 670 is coupled to upper triple clamp 530 and lower triple clamp 532, rubber isolator 682 and rubber isolator 696 serve to limit the amount of vibration transferred to removable windshield 164. This in turn reduces the amount of vibration sound that is experienced by the operator. In one embodiment, brackets 678 mount directly to upper triple clamp 530 and lower triple clamp 532 without rubber isolator 682 and rubber isolator 696. Further, rigid spacer 684 may also be removed.

In one embodiment, removable windshield assembly 670 is mounted to upper triple clamp 530 and lower triple clamp 532 as follows. The arrangement of rubber isolator 682, rigid spacer 684, and first coupler 680 are coupled to lower triple clamp 532. Open-ended slot 686 of bracket 678 is positioned so that portion 688 is received in open-ended slot 686. It should be noted that removable windshield assembly 670 may be rotated forward from its final position during these steps to ease alignment of open-ended slot 686 relative to portion 688. Removable windshield assembly 670 is positioned so that opening 693 of bracket 678 is aligned with the respective openings 695 in upper triple clamp 530. The arrangement of rubber isolator 696, rigid spacer 698, and second coupler 694 are coupled to upper triple clamp 530. Removable windshield assembly 670 may be removed by reversing the above-described steps.

Referring to FIG. 40, upper triple clamp 530 also includes ports 710 and 712. Ports 710 and 712 extend from a top side of upper triple clamp 530 to a bottom side of upper triple clamp 530 and serve as a retainer for wires of one or more wire harnesses which couple the components of either steering support assembly 510 or steering support assembly 512 to the remainder of the electrical system of vehicle 10 and vehicle 20, respectively.

Referring to FIGS. 41-43, the components of steering support assembly 512 are shown. Referring to FIG. 41, the base components of a front fairing assembly 168 are shown. A support 730 is provided which is coupled to upper triple clamp 530 and lower triple clamp 532. An operator side body panel 732 and a front side body panel 734 are also provided. Both of operator side body panel 732 and front side body panel 734 are supported by support 730 and are coupled together. In one embodiment, support 730 is a metal casting and operator side body panel 732 and front side body panel 734 are plastic and include one or more molded portions.

Operator side body panel 732 and front side body panel 734 support various components including windshield 170, front light assembly 172, left turn signal unit 660, right turn signal unit 662, an instrument cluster 740 (see FIG. 18), a pair of speakers 742 (see FIG. 18), a radio unit 744 (see FIG. 18), and other suitable devices. An exemplary instrument cluster 740 is described in U.S. patent application Ser. No. 12/015,435, docket PLR-05-1589.02P-01, filed Jan. 16, 2008, the disclosure of which is expressly incorporated by reference herein.

Referring to FIG. 42, support 730 is shown. Support 730 is coupled to upper triple clamp 530 and 532. Brackets 750 are coupled to upper triple clamp 530 and lower triple clamp 532 through a plurality of couplers 752. Threaded couplers 754 are aligned with openings 756 in brackets 750 and are welded to brackets 750. Couplers 760 threadably engage couplers 754 and couple support 730 to brackets 750. Couplers 760 carry a first rubber isolator 762, a second rubber isolator 764, and a rigid spacer 766. First rubber isolator 762 and second rubber isolator 764 are positioned on opposite sides of support 730 and isolate support 730 from upper triple clamp 530 and lower triple clamp 532 to reduce the amount of vibration transferred to support 730 and front fairing assembly 168 in general. Rigid spacer 766 is hat-shaped and carries first rubber isolator 762 and second rubber isolator 764.

Returning to FIG. 41, a portion 770 of front side body panel 734 is flared relative to the general contour 772 of front side body panel 734. Referring to FIG. 43, portion 770 makes an angle 774 with a construction line 776 that is parallel with centerline plane 116. In one embodiment, the value of angle 774 is about 40 degrees. In one embodiment, the value of angle 774 is from about 20 degrees to about 50 degrees. By having portion 770 flared, rain that collects on front fairing assembly 168 during rides is generally directed in direction 778. This assists in helping the operator to remain drier. As shown in FIG. 41, portion 770 continues along the edge of fairing 168 to a location 771 which is above the hands of the operator (see FIG. 12) and outboard of the hands of the operator (see FIG. 14).

Referring to FIGS. 44 and 45, in one embodiment, two-wheeled vehicle 100 includes a steering lock 780 built into upper triple clamp 530. Steering lock 780 includes a base member 782 which is coupled to upper triple clamp 530 through couplers 784. A lock core 786 of steering lock 780 is accessible through an opening 788 of upper triple clamp 530. Lock core 786 includes a receptacle 790 for a key 792. When the correct key 792 is inserted into receptacle 790, steering lock 780 may be placed in one of a locked configuration and an unlocked configuration. In the unlocked configuration, a lock member 794, illustratively a peg, is retracted into base member 782. In a locked configuration, lock member 794 is biased to extend from base member 782.

Referring to FIG. 45, when wheel 110 is in line with wheel 112 (front wheel 110 is parallel with centerline plane 116) peg 794 is positioned over top surface 796. If wheel 110 is turned to the right, lock member 794 may be extended beyond top surface 796, such that an attempted rotation of wheel 110 back in line with wheel 112 is prevented by the contact of lock member 794 with a first lock surface 798. In a similar manner, if wheel 110 is turned to the left, lock member 794 may be extended beyond top surface 796, such that an attempted rotation of wheel 110 back in line with wheel 112 is prevented by the contact of lock member 794 with a second lock surface 797. In one embodiment, lock member 794 is spring biased such that steering lock 780 may be placed in the locked configuration while lock member 794 is contacting surface 796 and then locked due to the biasing of lock member 794 to extend when wheel 110 is sufficiently rotated to either the left or the right. In one embodiment, lock member 794 may only be placed in the locked configuration when lock member 794 is not positioned above top surface 796; thus requiring the proper rotation of wheel 110 to the left or right first.

Referring to FIGS. 9 and 18, lock core 786 is accessible from the operator position for both vehicle 10 and vehicle 20, respectively.

Referring to FIGS. 46 and 47, in one embodiment, two-wheeled vehicle 100 includes a linked brake system 800 which includes a manifold 802 coupled to lower triple clamp 532. In linked brake system 800, a foot pedal brake input 804 is coupled to manifold 802 so that actuation of foot pedal brake input 804 not only actuates the rear brakes 808 (see FIG. 6) which are not coupled to manifold 802 but also front brakes 810 through the connection with manifold 802. The right side portion of front brakes 810 is shown in FIG. 4. Thus, an actuation of foot pedal brake input 804 applies braking force to both rear brakes 808 and front brakes 810.

As shown in FIG. 47, manifold 802 is coupled to a rear side of lower triple clamp 532 with couplers which thread into openings 822. As such, all of the lines from front brakes 810 to manifold 802 remain generally static as the relative placement of manifold 802 and front brakes 810 does not change.

Referring to FIG. 46, manifold 802 has four brake lines which are connected to the front brake calipers 810. Brake lines 830 and 832 connect to the left front brake calipers 810 and brake lines 834 and 836 connect to the right front brake calipers 810. A brake line 837 connects manifold 802 to foot brake pedal 804. A brake line 838 connects manifold 802 to a hand brake input 840. Brake lines 830 and 834 communicate fluid to the respective brake calipers 810 to actuate a center piston in the respective brake calipers 810 while brake lines 832 and 836 communicate fluid to the respective brake calipers 810 to actuate front and rear pistons in the respective brake units 810. Brake lines 830 and 834 are in fluid communication with brake line 837 through an upper fluid channel 842 in manifold 802. As such, the center pistons of each brake unit 810 are responsive to an input from foot brake pedal 804. Brake lines 832 and 836 are in fluid communication with brake line 838 through a lower fluid channel 844 in manifold 802. As such, the front and rear pistons of each brake unit 810 are responsive to an input from hand brake pedal 840.
